Cautionary Statement regarding Forward-Looking Statements

This announcement includes certain 'forward looking statements' within the meaning of, and subject to the safe harbor created by, Section 21E of the Securities Exchange Act of 1934, as amended, with respect to the business, strategy and plans of Perrigo, its expectations relating to the transactions contemplated by the Transaction Agreement between, Elan, Perrigo, Leopard Company, Habsont Limited and New Perrigo, dated July 228, 2013 (the "Transaction Agreement"), and Perrigo's future financial condition and performance, including estimated synergies. Statements that are not historical facts, including statements about Perrigo's management's beliefs and expectations, are forward looking statements. Words such as 'believes', 'anticipates', 'estimates', 'expects', 'intends', 'aims', 'potential', 'will', 'would', 'could', 'considered', 'likely', 'estimate' and variations of these words and similar future or conditional expressions are intended to identify forward looking statements but are not the exclusive means of identifying such statements.

Examples of such forward looking statements include, but are not limited to, statements about expected benefits and risks associated with the transactions contemplated by the Transaction Agreement, projections or expectations of profit attributable to shareholders, including estimated synergies, anticipated provisions or write-downs, economic profit, dividends, capital structure or any other financial items or rations; statements of plans, objectives or goals of Perrigo, New Perrigo, Elan or the combined business following the transactions contemplated by the Transaction Agreement; statements about the future trends in tax or interest rates, liquidity, foreign exchange rates, stock market levels and demographic trends and any impact that those matters may have on Perrigo, New Perrigo, Elan or the combined company following the transactions contemplated by the Transaction Agreement; statements concerning any future Irish, UK, US or other economic or regulatory environment or performance; statements about strategic goals, competition, regulation, regulatory approvals, dispositions and consolidation or technological developments in the healthcare and lifesciences industry; and statements of assumptions underlying such statements.

While Perrigo believes these expectations, assumptions, estimates and projections are reasonable, such forward-looking statements are only predictions and involve known and unknown risks and uncertainties, many of which are beyond Perrigo's control. By their nature, forward looking statements involve risk and uncertainty because they relate to events and depend upon future circumstances that may or may not occur. Actual results may differ materially from Perrigo's current expectations depending upon a number of factors affecting Perrigo's business, New Perrigo's business, Elan's business and risks associated with acquisition transactions. These factors include, among others, the inherent uncertainty associated with financial projections; restructuring in connection with, and successful close of, the transactions contemplated by the Transaction Agreement; subsequent integration of the transactions contemplated by the Transaction Agreement and the ability to recognize the anticipated synergies and benefits of the transactions contemplated by the Transaction Agreement; the receipt of required regulatory approvals for the transactions contemplated by the Transaction Agreement (including the approval of antitrust authorities necessary to complete the transactions contemplated by the Transaction Agreement); access to available financing (including financing for the transactions contemplated by the Transaction Agreement) on a timely basis and on reasonable terms; the risks and uncertainties normally incident to the pharmaceutical industry, including product liability claims and the availability of product liability insurance; market acceptance of and continued demand for Perrigo's, New Perrigo's and Elan's products; changes in tax laws or interpretations that could increase Perrigo's or the combined company's consolidated tax liabilities; and such other risks and uncertainties detailed in Perrigo's periodic public filings with the SEC, including but not limited to those discussed under "Risk Factors" in Perrigo's Form 10-K for the fiscal year ended June 29, 2013, in Perrigo's subsequent filings with the SEC and in other investor communications of Perrigo from time to time.

The forward looking statements in this announcement are made only as of the date hereof, and unless otherwise required by applicable securities laws, Perrigo disclaims any intention or obligation to update or revise any forward looking statements, whether as a result of new information, future events or otherwise.

No Profit Forecast/Asset Valuation

No statement in this announcement is intended to constitute a profit forecast or asset valuation for any period, nor should any statements be interpreted to mean that earnings or earnings per share will necessarily be greater or lesser than those for the relevant preceding financial periods for either Perrigo, New Perrigo or Elan, as appropriate.
